$MVCL – Move more than 256 bytes of storage z/OS JES2 Macros SA32-0996-00 |
|
Use $MVCL to generate a MVC (move character) instruction when you need to move more than 256 bytes of storage. Use this macro instruction in high performance areas because multiple MVCs (as created by this macro) are faster than using an MVCL instruction.
